Abstract: The Web continues to grow and evolve very fast, changing our daily lives. This activity represents the collaborative work of the millions of institutions and people that contribute content to the Web as well as more than two billion people that use it. In this ocean of hyperlinked data there is explicit and implicit infor-mation and knowledge. But how is the Web? What are the activities of people? How content is generated? Web data mining is the main approach to answer these questions. Web data comes in three main flavors: content (text, images, etc.), structure (hyperlinks) and usage (navigation, queries, etc.), implying different techniques such as text, graph or log mining. Each case reflects the wisdom of some group of people that can be used to make the Web better, for example, user generated tags in Web 2.0 sites. In this presentation we explore the wisdom of crowds in relation to several dimensions such as bias, privacy, scalability, and spam. We also cover related concepts such as the long tail of the special interests of people, or the digital desert, content that nobody sees.
